This is meant as a substitute for sys_clock_timeout_end_calc()
Current sys_clock_timeout_end_calc() usage opens up many bug
possibilities due to the actual timeout evaluation's open-coded nature.
Issue ##50611 is one example.
- Some users store the returned value in a signed variable, others in
an unsigned one, making the comparison with UINT64_MAX (corresponding
to K_FOREVER) wrong in the signed case.
- Some users compute the difference and store that in a signed variable
to compare against 0 which still doesn't work with K_FOREVER. And when
this difference is used as a timeout argument then the K_FOREVER
nature of the timeout is lost.
- Some users complexify their code by special-casing K_NO_WAIT and
K_FOREVER inline which is bad for both code readability and binary
size.
Let's introduce a better abstraction to deal with absolute timepoints
with an opaque type to be used with a well-defined API.
The word "timeout" was avoided in the naming on purpose as the timeout
namespace is quite crowded already and it is preferable to make a
distinction between relative time periods (timeouts) and absolute time
values (timepoints).
A few stacks are also adjusted as they were too tight on X86.

Add Atmel Pwm typedef so that when doing `Pwm * const pwm` definition
checkpatch doesn't complain about the position of the '*'. If not added,
we must define `Pwm *const pwm` to make checkpatch happy, but,
clang-format results in `Pwm * const pwm` (correct).

Add a derogation to checkpatch's 'SPACING' rule, which randomly returns
the following type of issue when STM32Cube HAL *_TypeDef are used:
-:10: ERROR:SPACING: need consistent spacing around '*' (ctx:WxV)
#10: FILE: drivers/adc/adc_stm32.c:806:
+ ADC_TypeDef *adc = config->base;
This derogation applies to all _TypDef structures defined in STM32Cube
CMSIS descriptions:
FMC_Bank1E_6_TypeDef
DMA_Channel_TypeDef
ADC_TypeDef

The pinctrl_soc_pin_t is used as an opaque type in pinctrl to store pin
configurations which are SoC dependent.

Add the ability to define architecture specific structures, notably
the ability to extend struct _cpu with per-CPU arch-specific stuff that
can be accessed with _current_cpu->arch.* similarly to _current->arch.*
for per-thead architecture data.
This is opt-in for architectures that want to benefit from this,
otherwise empty defaults are provided. A placeholder for ARM64 is
included to show the pattern.

This is now called z_arch_esf_t, conforming to our naming
convention.
This needs to remain a typedef due to how our offset generation
header mechanism works.

checkpatch expects typedefs to be suffixed with _t and has different
rules when typedefs are being used as arguments of a function. This
seems to be a known issue and defining typedefs in a file resolves this
issue.
